drorzel | June 5, 2009Physics World posted a somewhat puzzling story a few days back, headlined Ultra cold atoms help share quantum information:
Scientists in the US have demonstrated a novel "light-switch" in an optical fibre that could become a new tool in the communications industry. The device created by Michal Bajcsy at Harvard University and colleagues could be developed to share both classical and quantum information.
Quantum information systems could bring a revolution to global data-sharing, by encrypting, processing, and transmitting information using the properties of quantum mechanics. However, as…
bioephemera | June 5, 2009Thanks to SEED's matching Bloggers Challenge funds and some generous donors who gave me DonorsChoose gift certificates for Christmas, I got to push several worthy projects to completion this winter (by "topping off" their funding). That meant that I got real, snail mail thank-you packages from those classrooms.
At first I was a little ambivalent because I didn't really want the kids to spend their valuable classroom time thanking me. But then I realized that while writing those thank-you notes, they spend at least a few minutes thinking about the fact that a complete stranger cares about…
drorzel | June 4, 2009Tom Levenson has another excellent piece in his series on the writing of his forthcoming book on Newton, this one on hitting a wall:
The one bit of history specific to the Newton and the Counterfeiter project came when I hit a wall. I had written about a quarter of the manuscript by the autumn of 2006 - I'd even submitted a chunk of it to the departmental committee pondering my tenure case, which is as those of you in the academy will know, something of a fraught moment.
But as I tried to make the turn out of what was in essence back-story, my account of Newton's life up to the point of his…
drorzel | June 4, 2009When this first came out, I didn't pick it up, despite a glowing recommendation from Jennifer Ouellette, because NASCAR is one of the few things on ESPN that interests me less than baseball. I didn't really think I'd be interested in reading a whole book on the subject.
I saw Jennifer and Diandra on Bloggingheads a little while back, and she made it sound pretty interesting. And then I saw that she was giving a public lecture at DAMOP, and figured it would be good for airplane reading on the way down and back.
The Preface gives a nice description of how she came to write the book:…
drorzel | June 3, 2009For reasons that don't really matter, I learned yesterday that there is a marathon in Antarctica:
On December 12th, 2009, the fifth Antarctic Ice Marathon will take place at 80 Degrees South, just a few hundred miles from the South Pole at the foot of the Ellsworth Mountains. This race presents a truly formidable and genuine Antarctic challenge with underfoot conditions comprising snow and ice throughout, an average windchill temperature of -20C, and the possibility of strong Katabatic winds to contend with. Furthermore, the event takes place at an altitude of 3,000 feet.
That's one of the…
oracknows | June 2, 2009Three years ago, I wrote about what I considered to be a fascinating and promising approach to understanding tumor biology. This method involved understanding that tumors are in general made up of a heterogeneous collection of cells. Using this knowledge, it is possible to apply evolutionary principles to cancer, treating a tumor as, in essence, an ecosystem. Indeed, that is exactly what Maley et al did three years ago. They applied evolutionary principles to the precancerous lesion in the distal esophagus known as Barrett's esophagus by examining various measures of population diversity in…
drorzel | June 1, 2009Two noteworthy things in the meta-blog category:
1) The 3 Quarks Daily science blogging prize nominations are up, and it's a great list of sciencey bloggy goodness. If you're looking for a way to procrastinate, you could kill several days reading all 171 entries.
Once you're done reading them, go vote for your favorite. The top 20 vote-getters will be the shortlist given to Steven Pinker to choose the winners from.
2) Not on the list yet, but sure to provide some quality entries next year is the brand new X-Change Files blog from the Science and Entertainment Exchange. They're providing…
pharyngula | June 1, 2009I admit, I was initially put off by the mere title of Nick Lane's new book, Life Ascending: The Ten Great Inventions of Evolution(amzn/b&n/abe/pwll). I'm one of those many biologists who is adamant about the absence of direction in evolutionary history, and ascending just sounds too much like life climbing the rungs of the ladder of life, so I picked it up in a somewhat prejudicial mood.
Have no fear, though, I was won over. Right at the beginning, he admits that it is a subjective list; his criteria for including the ten chosen evolutionary innovations are that it had to revolutionize…
oracknows | May 31, 2009Want to know how Jenny McCarthy, J.B. Handley, other anti-vaccine advocates, creationists, quacks, 9/11 Truthers, and cranks and pseudoscientists of all stripes manage to be heard when they have no science, evidence, reason, logic, or facts on their side?
Sadly, The Onion knows: Oh, No! It's Making Well-Reasoned Arguments Backed With Facts! Run!
At first, it looks as though the forces of reason can win:
Goddamn it, nothing's working! It's trapped us in our own unsubstantiated claims! We need to switch fundamentally unsound tactics. Hurry, throw up the straw man! Look, I think it's going for…

"How does one distinguish a truly civilized nation from an aggregation of
barbarians? That is easy. A civilized country produces much good bird
literature."
--Edgar Kincaid
The Birdbooker Report is a special weekly report of a wide variety of science, nature and behavior books that currently are, or soon will be available for purchase. This report is written by one of my Seattle birding pals and book collector, Ian "Birdbooker" Paulsen, and is edited by me and published here for your information and…
bioephemera | May 30, 2009In the June Atlantic Monthly, Joshua Wolf Shenk has a long, moving article about what may be the longitudinal study of all longitudinal studies - the Harvard Study of Adult Development (Grant Study), begun in 1937. Its creator Arlie Beck planned to track 268 "healthy, well-adjusted" men from their sophomore year at Harvard through careers, marriage, families, retirement and eventually death - and somehow, from this glut of longitudinal data, to glean the secrets of "successful living."
But the portrait Shenk paints is as full of pathos as it is of success.
Delving into the case files, now…
oracknows | May 30, 2009One reason I (and most people involved in cancer research) don't like the frequently used term "cure for cancer." The reason is simple. Embedded within this term is the assumption that cancer is just one disease, when it is most definitely not. Rather, it is many diseases affecting many organs, each with its own mechanism of pathogenesis and each often requiring different treatments. For example, for "liquid" tumors arising from hematopoietic organs, the treatment usually consists primarily of chemotherapy, sometimes with radiation therapy in the case of lymphomas, while "solid" tumors often…

...and very well may not ever do again: tell you that I actually enjoyed reading a post on the Discovery Institute's blog.
I haven't commented on the whole Ida the fossil hoopla before now, but, like a good chunk of the science blogging community, I think calling the whole thing overblown is a serious understatement. Over at the Discovery Institute's media complaints blog, Richard Sternberg has a post up. And, damn it, I think it's actually not a bad bit of blogging at all.
pharyngula | May 29, 2009Go sign this petition to maintain the tools for sea exploration at Florida Atlantic University. They're trying to get a thousand signatures…we can do that in no time at all.
The Johnson-Sea-Link I & II submersibles are owned and operated by Harbor Branch Oceanographic Institute (HBOI) at Florida Atlantic University (FAU) in Fort Pierce, Florida. They are launched from the HBOI research vessel R/V Seward Johnson, a 204-ft ,purpose built ,state of the art platform redesigned in 1994 which displaces 1282 tons and has a 6,000 nautical mile range. An experienced captain and crew constantly…
oracknows | May 29, 2009I don't much like Oprah Winfrey.
I know, I know, it's a huge surprise to anyone who reads this blog, but there you go. Over the last four years, I've had numerous reasons to be unhappy with her, mainly because, as savvy a media celebrity and businesswoman as she is, she has about as close to no critical thinking skills when it comes to science and medicine as I've ever seen. Arguably there is no single person in the world with more influence pushing woo than Oprah. Indeed, she puts Prince Charles to shame, and Kevin Trudeau's is a mere ant compared to the juggernaught that is Oprah's media…
drorzel | May 29, 2009Why do we have two meter sticks taped together back to back?
What is the dark stain obscuring the markings between 30 and 70 cm on half of the meter sticks?
Where the hell are all the stopwatches?
Why are the demo magnets sticky?
Why do we still have six meters worth of a rusting, broken torsional wave demonstration?
Why are the springs sorted into drawers with color labels ("Springs-Red") when all the springs are the same color, and there's no particular correlation with the spring constant?
Why do we have five hundred yellowing sheets of newsprint?
Why are the metal projectiles stored in an…

Aptinoma antongil Fisher 2009
Brian Fisher has a paper out in Zootaxa this week describing a pair of new ant genera from Madagascar. Aptinoma and Ravavy are small ants in the subfamily dolichoderinae related to Tapinoma and Technomyrmex. Apparently, the backstory on these new ants is that ongoing genetic research from the Ant Tree of Life project revealed some Malagasy specimens to be rather distantly related to any of the previously described genera. On closer morphological inspection, Fisher found several differences that allow for the new genera to be reliably diagnosed.
Yet…
bioephemera | May 28, 2009It is no secret that 3 Quarks Daily is one of my favorite blogs. It's the first blog I told my boyfriend to put on his Google Reader (he'd already added BioE, but still). Which is why I'm overjoyed to announce that 3QD has created its own prize for blogging. It's called a Quark. Oh, how I covet the Quark - especially the Strange Quark. And the finalists are to be judged by the 3QD editors and their guest judge . . . Stephen Pinker! w00t!
Any blog post on a natural or social science topic published since May 24, 2008 is eligible. The catch? Nominations are only open until midnight on June 1.…
